Deuteronomy 33:8-10

LXX2012(i) 8 And to Levi he said, Give to Levi his manifestations, and his truth to the holy man, whom they tempted in the temptation; they reviled him at the water of strife. 9 Who says to his father and mother, I have not seen you; and he knew not his brethren, and he refused to know his sons: he kept your oracles, and observed your covenant. 10 They shall declare your ordinances to Jacob, and your law to Israel: they shall place incense in [the time of] your wrath continually upon your altar.
